Only when we were actually flushing the cell stats to a controller
would we free them. Thus, they could stay in RAM even after the
circuit was freed (eg if we didn't have any controllers).
Fixes bug 18673; bugfix on 0.2.5.1-alpha.

Modify callers to correctly handle these new NULL returns:
* fix assert in onion_extend_cpath
* warn and discard circuit in circuit_get_open_circ_or_launch
* warn, discard circuit, and tell controller in handle_control_extendcircuit

exit-policy/reject-private lists the reject rules added by
ExitPolicyRejectPrivate. This makes it easier for stem to
display exit policies.
Add unit tests for getinfo exit-policy/*.
Completes ticket #17183. Patch by "teor".

Performing lookups in both the client and service side descriptor
caches from the same rend_cache_lookup_entry() function increases the
risk of accidental API misuse.
I'm separating the lookup functions to keep the caches distinct.
|
|
Including the replica number in the HS_DESC CREATED event provides
more context to a control port client. The replica allows clients
to more easily identify each replicated descriptor from the
independantly output control events.
|
|
Adds an Enum which represents the different types of rendezvous
descriptor caches. This argument is passed in each call to
rend_cache_lookup_entry() to specify lookup in the client-side or
service-side descriptor caches.
|
|
Adds a control command to fetch a local service descriptor from the
service descriptor cache. The local service descriptor cache is
referenced by the onion address of the service.
This control command is documented in the control spec.
|
|
The HS_DESC CREATED event should be emmited when a new service descriptor
is generated for a local rendevous service. This event is documented
in the control spec.
This commit resolves ticket #16291.
|
|
Adds a service descriptor cache which is indexed by service ID. This
descriptor cache is used to store service descriptors generated by a
local rendevous service.
The service-side cach can be queried by calling rend_cache_lookup_entry()
with the 'service' argument set to 1.

This puts the init logic in a separate function, which we will need
once we have locking.
|
|
We used to use this when we had some controllers that would accept
long names and some that wouldn't. But it's been obsolete for a
while, and it's time to strip it out of the code.
|
|
Previously we'd put these strings right on the controllers'
outbufs. But this could cause some trouble, for these reasons:
1) Calling the network stack directly here would make a huge portion
of our networking code (from which so much of the rest of Tor is
reachable) reachable from everything that potentially generated
controller events.
2) Since _some_ events (EVENT_ERR for instance) would cause us to
call connection_flush(), every control_event_* function would
appear to be able to reach even _more_ of the network stack in
our cllgraph.
3) Every time we generated an event, we'd have to walk the whole
connection list, which isn't exactly fast.
This is an attempt to break down the "blob" described in
http://archives.seul.org/tor/dev/Mar-2015/msg00197.html -- the set of
functions from which nearly all the other functions in Tor are
reachable.
Closes ticket 16695.

This needs debugging; it currently breaks the stem tests.

The control port was using set_max_file_descriptors() with a limit set to 0
to query the number of maximum socket Tor can use. With the recent changes
to that function, a check was introduced to make sure a user can not set a
value below the amount we reserved for non socket.
This commit adds get_max_sockets() that returns the value of max_sockets so
we can stop using that "setter" function to get the current value.
Finally, the dead code is removed that is the code that checked for limit
equal to 0. From now on, set_max_file_descriptors() should never be used
with a limit set to 0 for a valid use case.
Fixes #16697

For FAILED and RECEIVED action of the HS_DESC event, we now sends back the
descriptor ID at the end like specified in the control-spec section 4.1.25.

Checking if node->rs->is_hs_dir when the router_status for the node does
not exist results in a segfault. This bug is not in any released Tor.

"+HSPOST" and the related event changes allow the uploading of HS

monitoring of HS descriptor upload status.

These commands allow for the creation and management of ephemeral
Onion ("Hidden") services that are either bound to the lifetime of
the originating control connection, or optionally the lifetime of
the tor instance.
Implements #6411.
